  Concise Synthesis of 5-Methoxy-6-hydroxy-2-methylchromone-7-O- and 5-Hydroxy-2-methylchromone-7-O-rutinosides. Investigation of Their Cytotoxic Activities against Several Human Tumor Cell Lines

  摘要：

  The synthesis of two novel 2-methylchromone-7-O-rutinosides is reported, and the in vitro biological activities of these compounds and their synthetic precursors have been investigated on the basis of their cytotoxicity against several human tumor cell lines. The synthesis features early stage assembly of the acidic labile glycosidic bond between sugar and 2-methylchromone aglycon under phase transfer catalyzed glycosidation conditions, whereas all the other standard glycosylation conditions specific to a wide array of rutinosyl donors bearing different anomeric leaving groups (e.g., SPh, OC(NH)CCl3, Br, OH groups) failed to furnish any detectable products.

  Short syntheses of cuniloside B and cypellocarpin C, (+)-(R)-oleuropeic acid-containing carbohydrates, are reported. Also disclosed are syntheses of the noreugenin glycosides, undulatoside A and corymbosins K-1 and K-2. Leaf extracts of 28 diverse eucalypts revealed cuniloside B to be present in all, and cypellocarpin C to be present in most, of the species examined. The widespread occurrence of these carbohydrate monoterpenoid esters supports their roles in essential oil biosynthesis or mobilization from sites of synthesis to secretory cavity lumena.
